I always clean the stains on my car window film personally, with a simple and effective method. Most stains can be removed, such as greasy fingerprints or dust spots. First, gently wipe with a microfiber cloth dipped in warm water. For stubborn stains, you can use a neutral car glass cleaning spray—spray a little and wait a few minutes before wiping. The key is to avoid products containing ammonia or alcohol, as they can damage the film's color or cause peeling. Daily prevention is also important. Quickly clean the surface after each parking to avoid stains solidifying under direct sunlight. If you accidentally get deep scratches or bubbles, professional repair is needed, which isn’t expensive—around a hundred bucks will do it. DIY saves money and hassle. The lesson I’ve learned is to be gentle and avoid using hard objects to wipe.

When there are stains on the sun film, I usually first identify the type: oil stains, water scale, or fingerprints. Oil stains can be effectively removed by wiping with a cloth dipped in diluted household dishwashing detergent. For water scale, a solution of white vinegar mixed with water can be gently applied, left for a while, and then wiped clean with a soft cloth. However, some stains like scratches are difficult to remove, especially flaws within the film layer, which may require replacement. When handling, it's important to use cleaning products specifically designed for window films to avoid corrosion from regular glass cleaners. Try to park less under trees to reduce risks like bird droppings. Address stains as soon as they are noticed to prevent them from becoming harder to clean later.

I think stain removal depends on the situation: for simple stains like fingerprints or dust, wiping with a clean damp cloth is enough. The key is to be gentle to avoid leaving scratches. Regular maintenance can prevent major issues; clean your window film once a week to maintain transparency. If you accidentally get hard stains, don't scrape them off forcefully—try a mild cleaner first. If that doesn't work, then consider seeking professional help.
